How to apply the Excel BITOR function

We can use the Excel BITOR function to get the Bitwise “OR”, which is the binary equivalent of two numbers. With the BITOR function, a binary representation of the numbers is used in operation and a decimal value becomes the returned result. The steps below will walk through the process.

Figure 1- Final result of the Excel BITOR function

General Formula

=BITOR (num1, num2)


  • Num1: first positive decimal value
  • Num2: second positive decimal value




Setting up the data

We will prepare the table as shown in figure 2 with the numerical values. The objective is to find the Bitwise “OR” of the combination of the numbers contained in each row.

  • We will input the numerical values for “number1” in the range B5:B9
  • We will also enter the numerical figures for “number2” in the range C5:C9
  • The result will be displayed in Column D



Figure 2 – Setting up the data

Applying the BITOR Function

  • We will click on Cell D5
  • We will input the formula below into Cell D5


Figure 3 – Enter the BITOR logical operation

  • We will press the enter key

Figure 4 – Applying the BITOR function

  • We will use the fill handle (the small square box at the bottom right of the cell) to copy the formula to the other cells. Click and drag the fill handle to Cell D9.

Figure 5- Final Result of using the BITOR function


=BITOR (num1, num2)

This function adds the binary version of two numbers. This function performs a logical OR operation for the binary representations of each number before addition, and finally, the result is displayed as a number.

For example, in our table, the binary representation for Cell B5 is 11 and Cell C5 is 1010.

Adding their binary representations, we will have:




Next, we convert, the binary representation back to a numerical value, by starting from the right using the process below:

1011: 1 X 23 + 0 X 22 + 1 X 21 + 1 X 20 = 11.

The arguments, number 1 and number 2 must always be greater than or equal to zero. Also, it should never be larger than 2^48-1.

i am trying to make a box change colors based on another boxes value. the issue is I need it to change based on multiple boxes depending on which one is most recent. example, box c4 is white unless box f4 is red, then it turns red as well, however if box g4 is green then c4 is no longer red but instead turns back to white.

I have Mac Excel 2016. I need to sort a column in a way which is neither ascending nor descending, and it doesn't concern days of week or months. It won't let me create my own order in custom sort.

Column C contains numbers only from rows 9 to 21. These could be either whole numbers - 1, 2, 3 etc or decimal numbers 3.5, 4.2 or 5.0. Minimum is 1 max is 5. If a cell C9 - C21 does not have a number then Cell H21 to insert 'ERROR' and conditional format cell to warning colour - red.
